Wezterm其实没什么不好，毕竟是原神语言Rust写的、也带GPU加速，本身也能作为muxer使用——但是在昨天晚上使用kitty提供的benchmark测试之后，我发现Wezterm的性能实在是不敢恭维🤬
执行kitten __benchmark__，然后发现Wezterm渲染ASCII字符的速度居然不到50MB/s…我用的可是M4 Pro啊kora
测下来发现Ghostty的文字渲染速度是Wezterm的2~3倍，虽然图片渲染速度有点拉——但我又不用终端看图，所以影响也不是很大。
另一方面，Ghostty在macOS上似乎是原生Metal，而Wezterm据我所知需要走WebGPU提供的Metal后端，虽然兼容性更佳但相比之下我更偏爱Raw一点的实现。
Ghostty用的语言也是比起Rust更Raw的Zig，这下更合我意了
尴尬之处#
我曾经是务实tmux反对者，反对原因除了tmux那反人类的快捷键设计之外，还有一部分是源于现代终端大多都支持分屏/分tab，日用基本是够了，tmux并非刚需。
Ghostty同样支持智能分屏和分tab，但是在macOS Tahoe上默认的tab栏是土到掉渣的Liquid Glass ！大部分情况下终端显示内容都是扁平化的，配合拟物化的tab栏，不统一的视觉语汇实在让人难以接受🤢
怎么办？只有杀
但是hide掉默认的tab栏之后，Ghostty就不支持分tab了👇
window-decoration
Configure a preference for window decorations. This setting specifies a preference; the actual OS, desktop environment, window manager, etc. may override this preference. Ghostty will do its best to respect this preference but it may not always be possible.
Valid values:
none
All window decorations will be disabled. Titlebar, borders, etc. will not be shown. On macOS, this will also disable tabs (enforced by the system).
怎么办呢？那就用tmux吧🤷🏻♂️
改键！#
为了让tmux的快捷键不那么反人类，可以考虑用Ghostty的快捷键取代掉tmux的快捷键。说人话就是，改掉Ghostty默认的快捷键，让它们给tmux发送tmux兼容的命令。
比方说，macOS上Ghostty默认用Cmd+t新建tab，而tmux新建tab的命令是Ctrl+b c，那么我们就把Ghostty的Cmd+t改成发送Ctrl+b c。这样tmux接收到Ghostty发送的命令之后，就会新建一个tmux的tab。
Ctrl+b其实是发送了b"\x02"，所以Ghostty里这么改就好了：
keybind = cmd+t=text:\x02c txt
比葫芦画瓢改掉其他快捷键，最终得到的Ghostty config大概长这样：

Ghostty支持自定义shader，顺手写了个 ↗
挺不错的。
